The normally bland face of Uranus has become increasingly stormy, with enormous cloud systems so bright that for the first time ever, amateur astronomers are able to see details in the planet's hazy blue-green atmosphere.
NASA's Dawn spacecraft is about to start its investigation of the largest member of the asteroid belt, 1 Ceres. It will take detailed images of the dwarf planet, and produce a geological map of its entire surface. But even ...
At the annual meeting of the American Astronomical Society last week, the booth devoted to a revolutionary new telescope called the LSST got a lot of traffic.
As the Hubble Space Telescope celebrates 25 years in space this week, NASA and its international partners are building an even more powerful tool to look deeper into the universe than ever before.
The closer we get to Ceres, the more perplexing the dwarf planet grows. NASA's Dawn spacecraft has found several more bright spots as well as a pyramid-like peak jutting out of the frigid world's surface.
Astronomers using NASA's Hubble Space Telescope have found that Markarian 231 (Mrk 231), the nearest galaxy to Earth that hosts a quasar, is powered by two central black holes furiously whirling about each other.
Astronomers routinely use the crisp view of NASA's Hubble Space Telescope to study all kinds of intricate details in galaxy clusters. By now you would think they've seen it all—but nature always has new surprises in store.
Wow! One of the most famous star explosions captured by the Hubble Space Telescope—several times—shows clear evidence of expansion in this new animation. You can see here the Homunculus Nebula getting bigger and bigger ...
Astronomers believe they might have observed the first potential signs of dark matter interacting with a force other than gravity.
